I think this is important to have. I actually had such a need

I'd think it would be useful because, in general, the higher
level classes or objects in a library depend on the correct
functioning of lower level parts of the library or other
libraries. Obviously it would be useless to run tests
for the higher level parts if the lower level parts
didn't work correctly. ( Hopefully the adjectives "higher level"
and "lower level" are clear, but if not, I could try and
define them or give examples. ) I'm surprised the topic
hasn't come up more often.
